Motion and Control

The Gas Spring that Stays Where It's Placed

04 January 2018

Anyone who has used a gas spring, such as those found in some car or van hoods or rear lifts, knows that they typically have two positions — extended or retracted (open or closed). But what if you want to be able to stop the spring and whatever motion it is controlling at some other position?

Enter the Easystop model of the Bansbach Easylift® line of gas springs. The Easystop spring is different than lockable gas springs that stay in place by opening or closing a valve. Using special valve technology, the Easystop spring provides a gripping force, allowing for stepless positioning. The only action needed to reposition the spring is moving it with an additional hand force — no opening or closing of valves or locking or unlocking is required.

As a result of this technology, the spring behaves a little differently than the standard gas spring. Instead of moving on its own to a fully retracted or extended position, the spring must be moved by hand to the desired position.

Two variants of the Easystop gas spring are available. The adjustable BY model is particularly suitable in the configuration phase for determining the necessary range of the holding force. By rotating the piston rod in the extended state, a holding force of up to 800 N can be achieved. If higher holding forces or if the holding force specification is known, the fixed version BX is recommended.

The Bansbach easylift gas spring configurator offers the possibility to easily and quickly create your individual gas spring from different components.
